"Midtown in Motion": A New Active Traffic Management Methodology and Its Implementation in New York City

摘要: This paper summarizes a new active traffic management methodology developed and deployed in New York City. The design, development implementation of the are driven by availability extensive real-time travel time data, upgraded ITS infrastructure need reliable robust signal control system for congestion complex urban environment. primary objective is to maintain mobility subject zone preserving capacity avoiding breakdown within zone. To that end, multi-regime adaptive strategies, ranging from strategically regulating demand balancing queue-storage ratio at critical intersections, work concert proactively manage congestion. Large-scale data (nearly 1 million records individual trips per day) utilized effective control. renders perhaps first large-scale framework uses travel-time based an grid network. In addition running autonomously, mode operator-in-the-loop allows operators interact with important timing decisions when pattern changes abruptly or switch policies involved. has been congested central business district Manhattan, initial deployment, called “Midtown-in-Motion”, includes core 110 square block Midtown 2nd Avenue 6th Avenue, 42nd 57th Streets. expansion currently underway, covering more than 270 blocks 1st 9th 42th Street.
